Atelier Yumia Proton Experimental

A new Proton Experimental update was released yesterday that fixes a couple of issues in games and makes some new games playable. Atelier Yumia's cutscenes will work again, while RiME's weird window behavior has been fixed. We can also now play Firefly Village and The Crew Motorfest, long loading times in God Eater 2 are fixed, and multiplayer is now working again in Farlight 84.

The new Proton Experimental update should automatically download if you already have the experimental layer. If not, just search for Proton Experimental in the Steam store on your Steam Deck and download.
